Sure. Because the velocity feedback granularity would be (inversely) proportional to the encoder resolution, you'd want the highest res encoder possible. Or, you could run this pid in a slower thread so you get more counts per cycle. Might be a little challenging to tune this loop, but would be an interesting experiment. Report back when you try it please!
